Be it known thatl, GLEN P. VHEATH, "a citizen -of the United States, residing? at Aurora, in the county of Kane and Stateiof Illinois, have invented-a new'an'duseful int provementin Adjustable I Ve1 tilato-1's," in

"Which the followingis z t-specification;

upwardly or may: be Withdrawn: and dis; 7 charged-into the atmospheref My invention relates to ventilators to be placed uponthe roofs' 'of buildings over or surrounding an opening through which the air from the room or rooms below will pass My invention is more particularly adapt}: ed for use; in the roofs or ceil ngs Ofthea tres, factor1es," stores, and the like, and is;

"specially-designed and "constructed so that it"may be' readily opened or closed, as d fy sired, and the arrangement is such that it may be only partiauy opened during in} clement" Weather and prevent rain; snow and other elements entering through the vent; Also the parts of myinvention are so constructed-and arranged that the closure may be a glass plate so as to-combine with the ventilator the advantages "of a sky-light.

Besides having the before 'imentioned advantages, a particular object-"of my inven-', tion is co-provide a more effective ventilator, capable of being adjusted so as topermit-of a free" and practicallyuninterrupted circui lation and passage of air therethrough and which may also be adjusted so as to exclude the elementssuch as snow andfrain and still be capable" of performing its i ventilating function, and -whichmay alsobe adjusted tocompletelyclose thevent; l n' 'connection With the possibility of completely closing the vent, 11 have also'provided an element whichuponthe occurrence Of fil- 'Wlll affect the complete closure of the device 'so as'to stop the draft and thereby to a certain ex-L tent retard or prevent therapid spread of the flames. r l

vatingjbar of angular cross section is slidabiy mounted in the openings guide hubs 16 and 17 so that it maybe recrprocated in a vertical direction, and a conical disk 19 is mounted upon the upper endof bar 18 by means of a socket 2O upon'the underside of the disk to; receive the bar.

Mounted in any suitable manner upon this disk 19;is a conical shaped hood or closure element- 21 the apex whereof-fits over theapex of disk 19, and the lower outer edge of the hood extends across and beyond theupper end of wall 10, as seen in Figure 1 of the drawings, and in order .to' reinforce the structure, I have provided a'suitable spider:

having brace-arms 22 that incline upwardly to the underside of hood :21 from a central t bossQB. surrounding and secured to the ad- 7 part of the skirt or shield jace'nt portion of bar 18.

:It will be seen by referring to Figure 3,

V hood'2l is or a diameter slightly less than thearnarrowest diameter of the opening in 7 t the inwardly turnedportion 13 of the skirt. or shield so that; the hood may be moved en tirely" through and above the'skirt 0r shield Whenever'it isdesire'dfto entirely open the ventilatomas illustrated in Figure 2 of the drawings; V During' 'ii1clement or stormy weather it is'desir'able to open the 'vent1'la tor, but to prevent the elements such as rain,

snow and the like, passing into or through wall 10 ,and to do this hood 21 is moved so that its lower edge is below the upper edge oft-he inturned portion 13, or about in the horizontal plane of the topof the vertical 12. I In order to raise or; lower the hood 2lito its'idesired positions, I have provided a yoke 24: having a'socketedi portion 25 that is se--' cured to the lowerend'of bar 18, and be-- tween the sides of theyoke'is'journaled a pulley 26 over the lower segment of which runsaa-ehaim'cable or the like, 27;. One end of this element'27 extends upwardlygifrom the pul1ey'26 to and is secured to one of thearms. of bracket 14', while the remaining portion of element 27 passes upwardly in the opposite directionfrom' pulley 26gto and through a pulley-block -28 :loosely' pivoted onjthe opposite arm of bracketld and then downwardly a suitable distance to be-in c on-. venientreach of persons within the build-.'

ing to'operate 'the ventilaton: The fall of element 27 passes through-la latch-bracket 2 9 so that the element may be engaged thereby to retain it in any adjusted position or to lock the hood in closed positionat night to" 7 prevent its being opened by unauthorized personsfrom the outside, who seekto; invade the premises. Also I have provided av fusible link 30' in element 27 so that in the event of fire the link will separateiandcause the hood 'togclose the ventilator of its 7 own weight. thus shuttingofi the draftthat ordinarily occurs with open ventilators.

The skylight "ventilator illustrated in Figure 5 of the drawings is, substantially of the same general construction as that above,

described, excepting that a glass closure is provided in lieu of the conical metalhood,

shown in' Figures 1 to 1, and in connection with this sky-light ventilator, I have shown another manner of elevating and lowering of wall 10 so that theformer may. telescope over the upper edge -of the latter when' theventilator is closed. a

In order to facilitate, the raising and" lowering of theventilator closure,- Imayem ploy a drum ,40 around which a 'bightrfif element 27 passes, andI mount-the arbor;
